To all whom if; f/iiag/ concern Be it known that we, Minor: E. Onsori and VIoTon C. Orson, eitizens oi the United States, V"esidine' at Grand island, in the County of Hall and State ot Nebrasla, have invented certain new and useiul :improveinents in Hydrocarbon Burners, oi' which the following' is a speciiication.

This invention relates to an improved hydrocarbon burner and seehs, among' other objects, to provide a device of this character which will be possessed of Superior heat generating qualities but which will consuine a relatively sniall quanity of tuel.

further object ot the invent-ion is to provide a burner which will function to ei'- tectively gasify the liquid fuel and wherein the iuel gas will be mixed with a proper quantity of air to produce a highly eoinbustible and practically sinokeless iiuel mit;- t-ure, the inixtu're only, being eonsuined.

Another object ot the invention is to provide a burner which will be noiseless in Operation, which may be readily eleaned, and which will be atlapted to the use of low grade fuels.

And the invention seelcs, as a still .iarther object, to provide a burner which will be eharacterized by structural Simplicity and which may be readily produced.

Other and ineidental objects will appear hereinafter.

In the accoinpanying drawings:

Figure 1 is a vertical sectional View'tahen inedially through our improved burner.

Figure 2 a horizontal sectional view on the line o' Figure 1, looking,I in the direction indieated by the arro vs.

In carrying the invention into effect, we einploy a circular bowl having` a fiat battoin wall 10 and an upstanding annular side wall 11 thicl-:er than the bottom wall. lntcg'ral with the botton'l wall is an upstanding aezially disposed air tube or .fine 12 terininatii'ig thish with the uppcr edge of the side wall 11, and forined in said side wall is an annular ledge or seat 13. Snugly but renjiovably :titting in said seat is an annular generating plate 141 which forms a elosuro for the bowl and cooperates therewith to define a retort chainber 15 within the bowl. The plate 111- is providediivith a flat bottom face stepped adjaeent the periphery of said plate to rest in the seat 13, and extending through the plate and through the wall 11 of the bowl are bolts 15 removably securing the plate in position. The upper face ot the plate H is of frusto eonical ontline, and forined in said plate is a central openine' Jnely aeconnnodating the fine so that a relatively na 1row annular gas passage 16 is defined between the inner circuniierence of said plate and the fine. At its outer periphery, the plate lies tlush with the upper end edge the side wall 11 and, as will be seen, the plate is gradi ally taperef iu thiclness from its oute periphery to the central opening ot' the plate. Fornied on said plate at its lower side are, as part'cularly shown in i rs oi? radially spaced depending to' lugs 17 terininating close to .l 10 of the bowl. Communicating with the retort ciainber 15 through the bottoni wall 10 of the bowl is a fnel inlet 18, and engaged with the tine 19 near its upper end, is an overtiow pipe 19. Any

approved ineans n ay be provided for regulating the flow oi" fuel through the inlet 18 to the retort chaniber while any approved automatic out oil? inay be provided in conjunction with the overflow pipe 19 to control the inlet of fuel and prevent the overilow of the bowl.

Snpported by the di fine and oi: a radius slightly less than twiee the inajor radius of the fine so that the periphery of the spreader lies substantially niidway aetv-.f'een the wall of the line and the out-er periphery 01"' the plate 14. Rising froin the conical upper side of the spreader is an apertured lugI 21 by which the spreader inay be lifted, and depending from the lower' side ot the spreader axially thereof is a spreader cone 22 extending into the flue i 12. Radiating fron'i said cone, as best shown in Figure 2, ai'e a plurality ot spaeing ribs or tlanges 23 notehed at their outer ends to lit over the upper end edge ot the I'lne. The ribs 23 thus support the spreador in spaced. i'elation to the Upper end ot the iiue and will maintain the spreader centered with respect to the ilue. will he observed, the lower i'acc ot the spreader is tlat. Consequently, the spreader gradually a pproaches the conical Upper i'ace of the plate Lt toward its outer periphery to dei'ine a restricted annular burner passage 24 between the periphery oi the spreader and said plate. The spreader is, of course, an integral structure.

ln use, liquid tuel is adinitted through nie 12 at its upper end is a circular spreader 20 overhanging said EGO the inlet 18 to the chamber until the fnel rises through the passage 16 and overtlows the inner margin of the generating plate 111. The fnel above said plate is then ignited. As the f'ncl is consnmed and the v burner becomes heated, the level of the fnel ie liqnid fnel in the cl? o, the heat is condneccd by the h ctly to the tnel. ,titfectire Lea'sitication of the tiqnid t'n-el thns accoinplished. Air assing up throngi the tine 12 snpplics a drart't so that the air is cansed to stril-e the spreader t) and ir fanned out ther by in a eirei ar sheet to tloW over the Upper end of the ne :ind con- 'seqnently, acror-:s the pass to become ntmed With th fnel gan hcne'ith the peripheral mai-gin of the spreader. this mixing of the air and fnel gas is accentnated by the presenee of the restricted lnirner parisage Ll-rt at the periphery of the spreader. Th ency of this re. -:tricted pa'ssage is to can'zw the sheet of air flowing benea h the ilat face of the spread'cr and the sheet of gas t'ewin yer the conical face of the plate let to in pinge each other at or nea' the tnroat of said passage, With the resnlt t1 t the air iltl'u and gas are coimningled to prodnce a highly comhnstible fnel mixtnre issning through said pass-age. lgnition then takes place so that an annnlar sheet of fian'ie is prodnced, which sheet of flanie is iinpelied by the draft through the tine 12 to t'loW over the generating plate 1-t beyond the periphery of the bewl. The burner is thns pecnliarly eicient and functions to prodnce a tlaine of intense heat. its Will be appreeiated, the epreader 20 may be readily lifted l wall and laying lower face tlat and :lpaced some d stance from the flat annnlar bottom of the bowl and provided With depending irojections terminating adJacent the said annnlar hott-om7 and having its npper face ontn'ar lly llared) means secnrin` the. lar plate. to the onter Wal andbottoin of the how and a` spreader supported upe-n the inner Wall and overhangand the inner portion of the annnlar f. .romprising a bon'l including a fiat annnlar betton'i, mner and onter circular Walls rising Iron the ii'iner and onter inargins of the burnerl of the character speeitied,
